I have to say that at your age, there is no medicine which can increase your height. Only surgery is the way ahead if you are really keen to do it. But you have to understand that limb lengthening is a time consuming and painful process, and it is fraught with certain complications, which you should be prepared to accept.

I can understand your concern.
There is no way to increase your height at this age now.
If you are willing to go under the knife, then orthopedician can help you with limb lengthening procedures.
But uts definitely not recommended.
Be happy with what you have.
Best regards.
